Question

give a detail description of mohr's method and volhard's method ​

Answer 1

Explanation:

In the Volhard method silver ions are titrated with a standard solution of thiocyanate ions. ... The excess silver is then back titrated using a standardized solution of potassium or ammonium thiocyanate with ferric ion as an indicator.

Introduction  This method determines the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added, a precipitate of silver chloride forms.  Ag+(aq) + Cl–(aq) → AgCl(s)  The end point of the titration occurs when all the chloride ions are precipitated.......
